British No 1 Andy Murray came from a set and a break down to beat Lukas Rosol at the BNP Paribas Open.
Murray prevailed 4-6 6-3 6-2 in an hour and 45 minutes on Stadium 1 at Indian Wells and will play another Czech, Jiri Vesely, in the third round.
Rosol broke Murray's serve twice on the way to taking the first set and did so again in the opening game of the second.
But that sparked Murray into life and the Scot reeled off six of the next eight games to level the match.
Rosol dropped serve to open the decider and Murray added the security of a double break before serving out victory at the first attempt.
"It was tough. I've never started well at this tournament, have always struggled early on with the quick conditions," Murray told Sky Sports.
"It's very dry in the desert and the ball flies through the air quickly. He was being very aggressive and hitting big shots. I just had to keep fighting and try and find some rhythm.
"Once I started to use my forehand a little bit more, I was able to dictate the points and started to feel better from the middle of the second set."
